I used to be that way too, but it’s a skill that you learn through practice. Like push yourself to get into things just a teeny tiny bit to start with for now. Then after awhile it’ll be easy to get to that point of toe-dipping, so then you push yourself to go in a bit more next time, and do that every time you’re at some activity, and then eventually you’ll find it easy to jump right into the deep end of every activity. But it does take some effort to push yourself in the earlier stages
Would you want to change it if you could?
