You’re working at a great pace on your own right now, so there is no reason for you to change. Why start working in teams? The other people involved could get you off your rhythm, and you might end up wasting more time than you’d like dealing with difficult personalities and the bureaucratic issues that evolve when there are more than two people working together. If you can’t stick to yourself right now, at least try to be the quietest one in the room.
Turn your perspective inside out, even though that could be difficult now. You sometimes get too entrenched in your own point of view. There’s a great reward for your heart and soul.
You need to focus all of your attention on your partner’s needs right now. Yours will get their chance soon enough. If you can take care of them selflessly, things will start to pick up in a big way.
Ideas just keep coming. Is it because there is no way you can implement them now? That could be, but you can write them down for future use. Things won’t be this austere forever.
