If opens the door of possibility. If means something might not work.
The problem is when we introduce only to the conversation. Only is conditional, restrictive and wishful. Only is predicated on the actions of others (chance). Only implies that something has to work.
If only we can get the boss to change his mind. If only we could get the right funding. If only we could get one more customer. I could be charitable too if only I had a million dollars.
If we are going to insist on sticking with things that can’t fail, what we are competent at, then we are living below are potential.
If failure is not an option, than neither is success.
