When Should We Have Our Life Together When I was a teenager, I thought I knew it all and had complete control of my life. When I was in my 20's I really knew that I had it all together. It wasn't until I was in my late 30's that I bought my first house and then I became a dad on my 40th birthday...That's when I realized that I wasn't as together as I thought. There's so much pressure on us to have it all together and it can take a while. Sometimes a person can be in their 50's (like me) and still not have it all figured out. A recent study took a look at the different ages that people should accomplish things in life and the ages are a lot older than they used to be.
