Need help beating friend?

okay so recently my friend has got really good at the things i was good at (art, running (100m) and discus) and to day was the athletics try outs i was really confident but he bet me by 2 seconds in the 100m and by 1.5 meters in discus he gets really patronizing when he wins he is like try hard and starts giving me basic tips as if i was new to the sports and in art i was really good at drawing but ive gotten not as good and he is getting choosen for all the art projects and stuff i guess im jealous but how can improve besides just practising so i can beat him next year
