The company you keep has a lot of effect on you. Many Investors who are also forum members would have stopped investing a long time ago or become inconsistent and uncommitted with their investment if they were not in this forum. There is something about being together with people with the same interest you have that I have noticed, their commitment can always motivate you when you feel like giving up, and help you make more stable decisions. Many investors who are not forum members will be finding it difficult to maintain their seriousness to invest regularly because they are doing things on their own. If many of those investors find this forum, it will be very valuable for them.
Companionship depends a lot. If you are wasting your time among friends who don't care or think about their future and always wasting money on useless things like buying new products i.e. shoes, food, clothes, etc. Then in their companionship, you will tend to do the same. In the same way when you will be reading posts on Bitcointalk about how motivated people are about BTC.
You will get motivated too even though you are so disappointed in the BTC and lost all but after seeing people's motivation you will gain energy and think to taking another start.
Even sometimes when I don't use to invest instead of investing I am consuming, but after reading member's posts I began to think that I should also save funds and start trading.
