We humans often think that at the end of the day, we could only look at the vast field where successful people often walk, talk, enjoy and get distressed because of various things in life that are happening to them as we speak. Now there, why are you looking at them as though nothing is happening to your precious life? Why can't you be that person who you're currently looking at, and scrutinize the way they do things? Truth be told, we are - beings - with insatiable desire even tho we have already achieved something worth bragging in our lives. But after every success that we achieved can only satisfy a small amount of our endless desire for success, but that's what makes human evolve faster, as the Ancients and Great Guros said," Our only greatest adversities is ourselves."
Yes, it's good that it fuels us to reach something better, and make us much more advanced in every field that we thread. However, sometimes we also forget the facts that we are only mortals, we are not immortals: we bleed blood if we are wounded; we grow older as the time goes by; we feel heartache for every sad story. So sometimes don't forget to see through the inner depth of yourself, learn to appreciate what you have done in your life! don't listen to the devil within your mind saying, "You can't do it, just give up."
(Fuck them, mate!)
Don't forget that, in every success that you attained in your life, were realized because of the sweat and blood that you poured down into your work every single day-- just to make it a success.
