Hello there @knowkrish :) Thank you for your congratulations wishes!
I am afraid to say I am not going to blog about what you requested. I mostly blog about Psychology because that is what I enjoy writing about. But, I can address your questions here on this reply :)
1 - My experience here has been a fascinating one. But, that is first and foremost because I write about what I love. That helps to keep things going. Throughout this year I have slowly learnt how to convey my topics to those who kindly take the time to read what I write, and in return I do the same to them: I read every single word of their comments and wholeheartedly interact back. It makes the whole Steemit experience more meaningful and worthwhile.
2 - The reason why I have so much SP - as you put it - is because my husband and I invested in STEEM. With that, we gain from the curation rewards and support other users as well as communities.
To an extent everyone is here for financial reasons, but focusing on people's wallet, on how much they make etc... can be a frustrating approach to this platform. All those who I have seen to abandon Steemit did so because they came here purely to make money.
On the other hand I have seen tens and tens of people who came here without SP, but with a lot of passion towards a specific topic, keen to get to know people, support others and have a laugh. These people work on making Steemit a better place, fighting plagiarists and scammers, they truly care not only about themselves, but about the entire system. I am also one of these people. In my opinion, the right question to ask is: how can I contribute to make Steemit a better place? I don't really know what you mean by success, but with the right mindset you will most certainly see recognition, followers, interactions and consequently support coming your way.
I hope this helps :)
