If there is a chance you can afford it, and you have always wanted to do it, then go for it.
To start with don't worry about anything except whether you like flying, and like it enough to keep paying for each lesson.
I have been told (and I believe it) that to make a small fortune in aviation you have to start with a large one. So don't consider investing - just pay and walk away after each flight.
You will be doing something you always wanted to, and after a while there will be fewer unknowns in your risk analysis and you might decide that an investment strategy is right for you - or you might not.
