Bucket list is a list of all the things you want to do before you die.
I believe every person should have a list like this. Of course you constantly keep mental notes on the things you want to do today, tomorrow or even in weeks, but sometimes we get so caught up in work and real life, that we forget about our dreams. If we make a list, at least once in a while, we will be reminded of the things we wish to do, and there is a higher possibility that eventually we will accomplish them.
Making a bucket list is a pretty simple.
There are different time-period bucket list, that you can choose from: you can make a seasonal bucket list about what you want to do, where you want to go in every season, or a yearly one, that way you are strictly limited in time.
But the ultimate bucket list is the lifelong one.
I think if you take the time to keep a list you should do it on a big paper, you can hang it somewhere you can see it, like above your desk and constantly add up new things to it.
If you want it to be more efficient, and creative: you can take a notebook, decorate the cover of it with pictures and places, and keep a list there. Also you can write about your experiences in-depth so you can re-read it whenever you want to remember it. That way this bucket list will truly be a lifelong memory.
