When I trained in Remote Viewing with the Probable Future course, it took me only two months to develop the ability however I made the mistake to stop the training when the ability appeared it eventually vanished within a month.
I noticed that pattern with many things, stopping a training when the ability appears doesn’t necessary mean that the ability will stay, I think that continuing the training for six months after a newly ability has been developed is safe and even after some maintenance is necessary ;the best maintenance to keep a psychic ability is to actually use it regularly.

I had no clear goal when I learned remote viewing, having clear goals will give you more motivation and once you complete your training you will be able to achieve your goals you had in mind with your newly developed remote viewing ability. There are dozens of applications to remote viewing :

Greg Kolodziejzyk uses remote viewing to predict the stock market and so far he is been successful at it, making a 100 000 dollars profit during the period 1998-2005.

I heard of another guy using Remote viewing to go play in Las Vegas casinos.

Some people use Remote viewing to make more accurate psychic reading.

Hobbyists interested in ancient civilizations use it to make their research.

Once you have a clear goal in mind of what you want to do with remote viewing it will be a lot easier to keep at it. Optimizing your chance of success

As far as psi functioning is concerned I always get better results when my mind is clear, quiet and with the two brain hemispheres synchronized. In practical terms, I tend to reduce or completely eliminate watching television, listen to music with headphone these activities tend to interfere with an efficient PSI-thoughts process.

In a nutshell, brain hemisphere occurs when certain audio pattern are presented to each hear, usually, it helps to improve brain function, relaxation and it also helps with the development of psychic ability to achieve this I use a couple of binaural beats CDs sometimes I work with Hemi-sync, Immrama or Mind-tek those are my favorites providers.

Frequent meditations should also be a part of a successful practise, because it simply help the mind to function better.

Energy Work

I noticed that when I do the N.E.W energy work routine (I do 25 minutes a day) after a while I tend to develop frequent episode of lucid dreaming and it was also confirmed by the developer of the N.E.W system Robert Bruce, I highly recommend the N.E.W routine it does help also with remote viewing by providing extra-energy which to perceive more clearly.

Good Habit and precision

Have a remote viewing journal with all the details of each of your session, also it is very important that when you want to remote view something you have to decide for a date, for example if you want to remote view the church in your street, the target is ‘My church at (address) today (date) at (hours)’ because the mind doesn’t care much about time, so if you aren’t precise with the time you might perceive things as it were 25 years ago or may be perceive things as they will be in a distant future.

Removing emotional block and limiting beliefs

Some of us are curious about the paranormal but in same case hold deep seeded fear about it, in such case these emotional blocks must be cleared before one can develop good ability. If you feel you have limiting beliefs regarding your ability to learn a PSI-skill I suggested you use the easy method of EFT to clear it. EFT is based on the idea that the cause of all negative emotions is a disruption in the body’s energy system. EFT uses tapping on meridian-acupuncture point to re-balance the system and eliminate emotional blocks.

The above simple tips should help to start a healthy practice.
