If you're tired of the struggle, tired of always putting in so much work for so little payoff... If you're running low on motivation, and need an inspirational boost to drive you to keep going...
then I highly recommend this video by Ben Lionel Scott, especially the first half. It put me back in touch with my ambitions, my dreams, and all I hope to achieve... it's a great reminder to never give less than your all.
If deep down you're hungry for success, and you want to unlock that power, then give it a watch and see how you feel.
I'm going to try giving this a watch before my next workout, and see how the extra motivation affects my performance. I'll let you guys know!
