Your accomplishments are a key part of what defines you, both to yourself and to others.   These successes are dependent on your belief the purpose or aim has been accomplished.

To be successful begins with understanding what success looks like (i.e., your purpose or aim).  If you are not perfectly clear on the goal or objective (what you are trying to achieve) how will you know if you achieved it?

In Isolation

In reality, however, if your only measure of success is personal and subjective without considering the views of others, you might not be as successful as you think.

Taken in isolation believing in the achievement of personal success can still be of value to you, however, it might not be a singularly defining factor from another perspective.

That is you may consider your achievements as important and valuable.  This can be personally motivating and lead to self-aggrandizement.

Unfortunately, if it is not a common view.  This leads to the question, “Have you been successful if it is not validated by others and from alternate perspectives?”

Your Happiness

Is success what you define it to be or is it defined by those around you?  Perhaps this is best answered by the rhetorical question,  “Who is in charge of your happiness?”

Remember those around you do not define your goals, they may influence them but you own them.  Living within the context of others approval might be needed to supplement your personal success but it should not be over powering.
