do something that scares you and something that inspires you

so i love playing sport and would do it every day if i could if my body would let me. However its because i love it so much that i do it.... as a side effect sport also keeps me fit because its exercise that i don't need to think about doing.  its almost incidental  So why don't you find something that you love doing and see if you lose weight.. got to be better than doing exercise because you have to lose weight. If you have that mindset going in not only will you hate it but your body will hold onto the weight because you subconsciously told yourself something.
Now the other side of the coin is being scared. So how do you step outside your comfort zone every day. I think what is the worst that could happen, what's the safe option and what's daring but I'm likely to get away with. I go from the middle daring and take a step towards the unknown. And you know what. You learn something new generally and it never turns out as bad as you think it will .
