Learn a new skill.
Whether you love or hate your job, why not prepare yourself to take on a future career path that you are interested in? Develop a new skill and invest your energy in fostering it. If it’s also something that could help in your current role, ask your employer to send you to a seminar or pay for an online course. At the very least, you can start to prepare for your next job down the road while learning something that is of interest to you.
