Determination is my passion. For e.g., looking for something when I know it is right here and making sure that I find it. That is something which makes me truly happy about it. does that tell what i'm good at? how can i make my life useful with this?

this is a great ability and thing you have , honestly you had determination and you were determined to find something you know is there like a chance or choice etc. It gives you more options you are more able to do things , live life to the fullest and not straight away try to get out of the situation because theres many obstacles , this makes you stubborn and willing and is very good in life , things come out of working hard and determination so although I can’t really say what your good at , I am sure you are good at a lot of
things due to having the spirit to go far :)
