A few days ago, I was lucky enough to listen to a presentation made by a renowned author and ex-military man. It wasn't a motivational speaking seminar, but he spoke on a variety of topics.
One thing he said really resonated with me. He said that we always have a choice in every single situation. He also said every choice has some consequence, positive or negative. Take the example of someone asking you to go somewhere or do something that you don't really want to do.
You have a choice. If you really don't want to go, don't. Of course, this may have some consequences that you'll need to weigh.
On the other hand, if you do decide to go, take responsibility and go with an open and positive mind.
Where we get in trouble is in the middle ground. We go, but we're resentful and negative, and we blame the other person for 'making' us go. This negative attitude means you have a rotten time and chances are you'll ruin the other person's time as well.
The message is simple. Go or don't go. But take responsibility either way. If you do decide to go, let go of all the negative energy and thoughts. You never know, with an open mind, you might even enjoy yourself. Some people live their lives blaming external factors, people and circumstances for their woes. This perpetuates the notion that we are living a helpless existence. Taking responsibility and realizing that you've made a choice is very freeing and often opens you up to new and positive experiences. It also frees you to live in the moment.
Food for thought.
