Its not only you, every person passes thru it at least once in a life time. Some people get a way real quick some people keeps looping around the same mess. Reading your line I could only say u haven’t found your passion yet. Having said that I myself haven’t found yet, so I m your an alter ego as far as this topic concerned but its slowly changing for me now. So many things pops up into my mind, I get infatuated for a while, and it lessen subsequently as the time passes, that’s where I m lacking to find out my passion. Many times I got intertwined in thought n couldn’t wind up to something concrete. Another thing I believe the true cause of not being able to pin point what we need is uneasy anticipation of future. We expect too much from future and put bare effort on present or we put effort on such things which do not interest us and the reason could be we are doing this ‘cause someone else want us to do that. Usually we are so occupied thinking what to do or what if it happens in the future and we forget what we supposed to do at the moment.

So to answer your question is nothing else than your true self can motivate you better, rest only accelerate you to speed up as a catalyst which do nothing if u choose to stay inert. So learn to value yourself, you are the most important person for you. Be cautious about the negative catalyst like jealousy, overconfidence which is simply arrogance, hatred, and negativity as some people here on sajha are trying to put forth. They may call it opinion but I smelt like onion which is very hard to cut thru. And the opposite, appreciation, positivity adore you to stay motivated

I might be the catalyst to you but u r the real motivator of yourself. For me ever glowing smile in the face of my parents and fiancée puts extra vigor and I agree with no-more-crush bro but I wonder how many crush he had in the past.

Steve Job was so true saying this and I don’t mind repeating this again if it motivates you a little bit. “Sometimes life hits you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don't settle.
