It's best to start at a higher level when participating in competitive sports.

False.

Explanation:

The statement is false due to several reasons. Competitive sports require excellent skills as one has to battle the extreme competition and if one fails to meet the expectations, the consequences are unanticipated. Thus, it is always suggested, to begin with, the lower level and polish your skills with experience and then move on to a higher level. Straight away jumping into the higher level may lead the sportsperson to depression, anxiety and lack of confidence due to poor performance as a result of lack of experience. Thus, the statement is false as one is recommended to start with a lower level and grow and learn further and accomplish their dreams.
