RE: This is my first post.. let me know what you think. :D

Hi manojpatel! It is so great and I feel so happy that I have inspired you to start posting your own content. Since I am new as well, I would recommend looking at the comments other folks have given in terms of tips and suggestions.

Overall to summarize some of the first tips I would recommend are:

Post on things you are passionate about and have your own personal experience in.
You can create a post asking people for the type of content that they are interested in seeing.
Share your interests and types of videos that you could create to give folks options of the content that you could potentially create.

I think these are good starting points that I have personally taken. Definitely keep in touch with what you end up doing. I will follow you! :)
