Wow!! You know, i am just so excited after reading your post and I can't tell why. You are at the right place and at the right time.
Your wish of becoming a good content creator is already a settled matter, if only you will give yourself to learn. There are many communities here that can help you achieve that in no time. The first I would recommend is Hive Learners Community. I learnt almost everything I know today from that community.
