Direction is more important than the current position
Where you want to go is more important than where you are.
Where you are might be a situation that you dont like -- there might be a lot of problems associated with it.
But what I am now thinking is that I have been making the mistake of cursing where I am for all the pr0blems I had. That is not the right approach. I should instead try to look in the direction where I want to go, and think about how to go about it. If that involves solving some of the problems you currently have, then solve them. This keeps you in track of where you want to go, and also prevents you to just keep bickering about your current situation and doing nothing about it.
A simple example would be that we can try to curse us for not having a particular set of skills that you would need to get selected for nice jobs. The way to overcome is to think about it, and ask yourself really what you want to do -- and then try to head in that direction, by developing the required skills.
This simple (kind of obvious too) advise would help me in many ways I think.
