How much patience is too much?

I began to wonder about something tonight - oddly, a night when I have full blown cold, studying for a midterm, and I guess...online stuff. Perhaps it has been hidden under my subconscious mind and decided to bring my attention at the most random night. Yes, I am an odd person.

So how much patience is too much? Is there a numerical measurement to determine patience gone too much? Or can such patience ever become too much? I have been questioning myself about that lot lately.

Here is the scenario: you are naturally an uber-patient person. You are happy with your life generally until something finally hit your head and begin to think whether this is what you really want. You feel like you have discovered the happiness until reality decided to hit on your face, and you begin to doubt. You know there isn't much you can do to change the present situation, yet you feel the urge to bring it up anyway. You realize that you may have to continue a certain life for awhile but wishing it could be better. Nobody's fault, merely a mutual decision. Regardless of your random behavior, there isn't much you can do about it. You just wait...hoping things will get better or more like wishing it was like the past. You be patient for as long as you could handle.

Questions is, what if you feel like the patience is running out slowly? Or does limit exist in patience? I don't know, but it has been painlessly bothering me. I simply wish my life was a little more definite than now. I have lived too long with uncertainties - not just one but many.

What would you do?

PS- I think I'm just frustrated or need to quit thinking too much... :/
