The truth is that if you choose to not be happy, you won't be happy no matter where you live, or what day or year it is, or what pastor you have or what church you pastor. Paul said that he had learned to be content in whatever situation he found himself in. We need to condition ourselves so that we see ourselves being satisfied right here, right now. The point is clear. We need to learn to live in the hear and now, not live regretting all our past mistakes, nor waiting for perfect conditions in the future.
Contentment is for today.
Another ingredient for contentment is to learn to discern between needs and wants. It is very easy for all of us to get our wants confused with our true needs. Beside there being hundreds of things to buy, there is usually something they need, and many more things they want. It's difficult because many older people already have many things, don't particularly need anything and in actuality really don't want anything. When we really stop to think about what it is we truly need in life, we realize we already have all we actually need.
