I heard some wise advice once.
I can't remember exactly who said it, and it seems to be untraceable in terms of Google searches. The tip is that there are times in life when you might feel stuck, and it's best to get moving any way possible. The basic idea is that there are instances in life when you might sense excitement and energy with a different group of people, in a different job, or in a different location altogether, and instead of staying put you have to move.
Another way of saying that is: If there is a better place, situation, or circumstances where hope and joy are in abundant supply, it is always better to pursue that instead. You have to put yourself in the path of that new excitement and energy.
This applies to situations where you might be feeling isolated or alone. It's too easy to decide to stay in a certain situation or to put up with a job you hate in hopes that things will improve. And, quite honestly, they might improve. If you are in a relationship that seems to be constantly degenerating, it's OK to stay hopeful that something will change, that the relationship will improve. If your job is the worst, it might get a little better.
The trick is to recognize when that will not happen. We all like to stay hopeful about a job, a friendship, a town where we live, an organization that has captured our attention. Hope seems to be baked into our DNA, and I can't imagine the alternative--to always have the mindset that things won't work out or that they will continue to degrade.
That said: If there is a new situation that will provide a better fit, it's important to make a change. This does not always mean physically moving, by the way.
It can be a change in the people you are around, the job you have, or the organization you're a part of. It can mean a change in how you allocate your time. As humans, we tend to stick it out for far too long and put up with way too much. We keep trying to make something work, especially in terms of our jobs.
Most of us hate change. Change puts us in an unknown and unpredictable situation, and we resist that because we don't know if we will be successful. What we know, even if it is a terrible situation, is at least known and predictable. It goes back to the human condition. We feel we can control the outcome of the known and predictable. It must be better!
Frequently, it isn't.
A terrible situation can lead to isolation and loneliness, a sense of being disconnected. Yet the curious thing about movement and change is that it can reinvigorate us. The simple act of changing and moving can restore connections because you are suddenly thrust into something new and unpredictable and you have to rely on others again.
And, even more than that, the change puts you in a new situation where you can tap into whatever momentum is already pushing other people along. Say it's a new town or a new job--you suddenly get wrapped up in that opportunity.
Of course, you can't keep changing and moving. Choose wisely. Wait to see if things will work out. However, avoid the trap of sitting, waiting, and wondering. That never works.
