Having support from other people, positive words of encouragement, or other kinds of thumbs up for your efforts is nice, but you can’t rely on it.
Sometimes people get jealous of the things you are able to achieve, or are envious that you are able to achieve something they cannot.
Sometimes people just aren’t in the mood, frame of mind or emotional space to validate something that is important to you creatively.
Sometimes they don’t see what you see, the effort, incremental improvement, or the pride in success of some new concept or technique.
You’re not always gonna get kudos, and you need to be okay with that and just keep going.
