Yes you can.
You can take three times as much.
Don't tell yourself you can't.
Don't sell yourself short.
When clients tell me they can't take it anymore (the "it" being their job, marriage, or weight.), I tell them they are lying to themselves.
What we have to deal with on a daily basis is nothing compared to what we can do.
We can endure so much more that we allow ourselves to believe.
Now, you may not want to take it.
And you don't have to.
But you can.
So don't lie.
You can endure.
And in many cases, it's worth it to do so.
