Define "Happiness" as your success criteria. Don't tie happiness with anything materialistic, like "Learning ML", Spinning up a Bot in AWS, Doing that cool BlockChain crashcourse, demos. Do something to the person you care about, (or) the persons who care about you. Like, go for a walk with them. Speak about all the moments that you missed to recognise/understand/been insensitive to them. After all "Succesful" is like a user story that your product manager promised to fill the "acceptance criteria" for. That will never have an end. Succesful is a state of mind like depression and you have the choice to choose between being succesful or depressed in whatever you do. All the best.
