Fate...leads to what?

Are the things we put so much hard work into really worth it??? Each any every minute we spend fighting for something....is it worth it? The pain, money, the sweat...and most important of it 'time'.... Do u sometimes feel like fastforwarding this time and see if your hard word and time really matters in the end? What if all these are just illusions? What if you are just wasting your time toilling for it while you have something else waiting for you in the future? But again....if you dont give your best you will blame yourself for not acheiving it....what if you dont get it after giving your best? Then when you look back will you blame yourself...that the fight wasnt enough...or you didnt give your best....or whatever happened is fate? What if we could just fastforward the time and see if the fight is worth it and then return back and fight for it....
