All blame is a waste of time. No matter how much fault you find with another, and regardless of how much you blame him, it will not change you. The only thing blame does is to keep the focus off you when you are looking for... reasons to explain your unhappiness or frustration.
The joy is in the getting there. The beginning years of starting your business, the camaraderie when you're in the pit together, are the best years of your life. So rather than being so focused on when you get big and powerful, if you can just get the juice out of that... don't miss it.
You may not like the idea of putting money into a home when you're moving out. But it's demanded by the market. You need to show it off. You don't have to rip out the kitchen and bathroom. But maybe replace the tiles or the countertops. Get professional advice.
