Get some extra income with some extra work!
You should never rule out the possibility of picking up a side gig as a way to earn an alternative income or just to be able to boost the retirement funds you have. After all, a lot of people are very used to having to go to work every day, and the very same people find it a bit jarring to have to stop working while they are retired, so this is also a great alternative to finding yourself in a position where you have a lot of time on your hands.
Not to mention, this is a great way to supplement your Social Security payments or even replace them if you are unfortunate enough to not receive such payments. Do not think of any side gig you will pick up as hard work or even something degrading. These types of jobs are meant for retirees to be able to make use of their talents and skills in order to make an extra income out of them. Sometimes even something as simple as knowledge can bring you a pretty alternative income since you can teach classes or just end up tutoring.
If you ever find yourself needing some extra cash in retirement or bored of the routine, think about how you can turn your skills into something marketable or needed and pick up a side gig to give yourself what you need while doing something you know and love!
