Natural talent and telekinesis.
Assuming I can improve it by just getting stronger would only encourage my already disciplined gym habits and I would be twice as strong in any circumstance where I can make direct contact with something as well as use my telekinesis on it.
Natural talent just because getting past the "I'm so bad I'm not having fun" stage of literally any hobby/skill is the hardest thing for me to overcome. I hate every second and I usually quit before I develop enough to enjoy whatever It is.
