TB Hill sets

Did 6 sets of TB hill loops today.. just couldn't get e right kick today.. tried hard to push but legs just cldn't coordinate.. dragging myself loop after loop.. felt pain on the outer side of right knee after the run..

Conclusion: simply too lazy n rested for too long during hols.. oops..
Task: how to keep my mind motivated to complete all the sets???
