Every moment is a universe in itself, complete and whole.
When you are young spend at least 6 months to one year living as poor as you can, owning as little as you possibly can, eating beans and rice in a tiny room or tent, to experience what your “worst” lifestyle might be. That way any time you have to risk something in the future you won’t be afraid of the worst case scenario.
I think the key to success is to be passionate about what you're doing.
The most important thing in investing is to have a clear plan and stick to it.
