Invest in yourself.
You are your best investment. You are worth the risk. You will pay back dividends far and above your wildest expectations.
Back yourself to the point that you are positioned to leap high enough that you don't know exactly where you'll land next. Of course you have decided on the direction of your leap but the outcome will be decidedly hazy if growth is to occur. It takes guts to allow for the unknown to emerge in this way.
This takes the kind of investment of money, attention and time that only you'll afford for yourself.
Others might try offer you less sustainable sources of investment that can play as a placeholder or substitute until you are ready to launch things for and by yourself.
Back yourself. Invest in the infinite resource of you.
