That I you're struggling like a fish trying to complete a marathon, it is not because you're lacking something. Even shark is out of breath. the only think that you need to do is evolving. it can be tough. took fish millions of years of evolution to get there but they did finally. maybe for human being they would be a mental shorcut(pun intended). nobody knows but the hardest part of everything is life is getting over yourself.
your ego and your temptations.To other people it might seem like that I'm rambling, but it's just a common practice to sort my mind untile I find the right platform to get things off my chest.
