Alright. I hear you. You probably belong to the working class. We need our jobs because it's actually what we are destined to do. We attend school, go to College, then next -- find a job and make money, to support yourself or your family, to send kids to school, so they would go to College, so they could get a job to make money, so they could support themselves or their family, send their kids to school (technically your grand kids), and it's a neverending cycle. Unless, you are one heck of a Gazillionaire, or a business tycoon, or a Mafia member, an heiress, then you are exempted to read this advice.
There is so much more beyond going to work and making money. We can still make our job the happiest thing that ever happened to us if we:
1. CONSIDER THE PAY
Find the one you deserve pay-wise. Consider the salary if it is adequate enough to cover basic needs. You wouldn't want to be underpaid with unpaid bills, would you? It doesn't have to be a high-paying job, but at least enough to support the house.
2. MAKE SURE YOU CAN ACTUALLY DO IT
As for the skills, don't be over-confident that you will kick ass and be on top. Overdoing things is sometimes not good, especially in workplaces with low 'appreciation meter'. There is no harm in trying to learn things, that is actually great, but if it something that brings work stress, steals your family time, and takes away your sanity -- then you better be thinking now.
3. TAKE YOUR BREAK
Remember that employers don't pay our lunch breaks, though some are kind enough to pay morning and afternoon breaks. Workers tend to be more productive when they take their breaks. It gives them time to replenish not just the physical energy, but also their mind and psyche. It doesn't matter how you do it -- slack around, eat buffet, meditate, do yoga, nap, stalk someone, as long as you take it.
4. EXERCISE GOOD COMMUNICATION
This is simply derived from the idea that any misunderstanding can be straighten through effective communication. Be open to your boss and co-workers. A secret to a happy workplace is the people. Personalities vary and you definitely can't please everybody, but communicating in a right manner will prevent conflicts that may arise.
5. GET AN OUTLET
I'm not going to give you a shopping advice. Sorry about that! What I mean is you should have an outlet where you can get stress out of your system. It can be sports, book club, dinner nights with friends, woodcrafts, witchcrafts, etc.
