Sometimes all our "self-help" stuff just doesn't seem to work anymore, and we want to scream out obscenities and just drink lots of beer and watch bad TV. And that's okay to do sometimes. More importantly, when this happens, we should notice. This is an important time...when we need to do a re-set more than ever.
That might be just taking a break from whatever it is that has been driving us batty, or recognizing that if we keep getting stuck in something, maybe it's because our approach isn't right, or the "thing" we're stuck in isn't right either. Like a bad relationship, it's just not supposed to be that hard. If it's a lot more work than it is fun more than 50% of the time, it's time to get out (of the relationship, the job, the project). Probably less than 50%, but let's leave it at that.
The hard part is knowing when to quit. It's not as simple as just giving up, it's that we are following our gut that something is not working. Often we tend to fight that gut feeling and try to FORCE something to "work" because some part of us really, really wants it to work.
The definition of insanity is trying the same thing over and over again and expecting different results. Are we humans mostly completely insane?
We can take back control of the tangled web of patterns our brains get us into. But, you must ask yourself, do you really want to? I hope so.
