A sentence fragment...
It does not sound right, therefore it is not complete (fragment). Run-on sentences are complete, yet they are extended to much.
<u>Answer:</u>
It is very important how we look at things.
<u>Explanation:</u>
Everyone grows and evolves with the experiences in our life. But at times, these experiences hold us back in performing something. May be our family, our fears might alter our decisions in doing something. But it is very important that to move ahead in life, we need to take our instinct very seriously.
Even though we did not have a good experience on something in the past, doesn’t mean it will repeat. We need to have a positive point of view and go ahead. If we look at it positively and with determination, we can defeat our fears and be successful.
If the sentence in question is a statement (ends with a period), I would probably "however" as your transition word.
