Answer:
See explanation for answer. 
Explanation:
As far as limits go, I have ADHD. So I struggle with meeting goals on time, especially long-term goals. I do believe in myself very much but I have my limits such as everyone else does. I lose patience and focus easily. So if my goal doesn't seem in reach I generally quickly determinate it or procrastinate with it. Seeing other people achieve their goals does make me feel like I can never do enough sometimes. Most of the time however it is my own nature that keeps me from meeting and accomplishing my goals. My self-determination is not the problem, I am plenty determined or just as determined as others to meet my goals, I just struggle more internally to do so than others do. 
I hope this helps!
Have a lovely night!
