When we invest time in what we don't believe, we waste time because we live complaining and frustrated by the things that go wrong because we wanted it to happen the way we planned it to be.
Invest in what you believe most and that person starts with you... it's just you!
By investing time in yourself, you get to know yourself better, and then you start chasing what is good for you. People can take you halfway, but you are the one who must go along the trail and the last steps you take is just you.
When you understand that no one needs to believe in your dreams but yourself, because you are the one who needs and will make them come true... then you stop chasing after being noticed or applauded by others.
Instead of being influenced by others, learn to influence people... seek everything that makes you good, avoid wasting your life trying to fill your life with illusions.
Madness would be doing the same thing almost daily and looking for different results, it is clear that the result would always be the same.
Know everything that satisfies you and start investing in it, and you will be happy in everything you do.
