Think about the time commitment.
If you're very busy, you may not want an incredibly time consuming hobby. However, if you have a lot of free time on your hands, a hobby that requires a lot of time may help you stay busy.
- Things like reading, drawing, or crossword puzzles can be done in small spare moments. You can do these things on your lunch break or after dinner at night. They do not require a lot of time. These may be good if you're already busy.
- Other hobbies require a great deal of free time. Something like gardening, for example, must be done for a set number of hours each day. If you have a lot of free time to fill, opt for a hobby like this.
