You're right @dobartim, you can't upvote all those huge number of followers. But what you are doing, imparting knowledge to people to make them successful is the best thing you can do for them.

I'm sure that every of your student who follows your principle will not complain whether you upvote them or not. Because the principles and strategies you share with us in Steem School are enough to make people succeed here.

Thank you so much. Hope you enjoyed your lunch!
