A big problem can cripple a business. It can stop it from ever getting to where you want it to be and can eventually bring it down. The worst thing you can do is hesitate and procrastinate and sit on the thing because you don’t know how to solve it.
Just because you’re struggling to find a working solution doesn’t mean there isn’t one. Almost certainly, there will be a solution because I very much doubt that your problem is a first and that someone, somewhere hasn’t already solved it – it’s just a matter of finding it.
