1. Think about what motivates you

The meaningfulness of one’s work is always important. While it’s nice to know that the work you do has a positive impact on the world around you, make sure that you’re not simply changing careers to avoid pet-peeves such as office politics.  
These things will tend to crop up in most very job, so make sure to not fall for ‘grass-is-greener’ syndrome.

Understand that every job is challenging, and a career change might present you with difficulties you can’t easily overcome.
In short, ensure that you have the mental fortitude to overcome any challenges that may lie in your future, and make sure that your new career provides enough incentive to keep you motivated and working towards your life goals.

2. Have a backup plan

Picking up a new career takes time, and it’s impossible to plan for every eventuality. You’ll need to have a contingency plan to fall back on if things don’t work out.
Before changing jobs, think about how you might get back on your old career track if your new career doesn’t go as planned.
It may be difficult to start a new career, but it will be infinitely more difficult trying to pick up the pieces of a failed career change if you don’t plan in advance.

3. Consider your financial situation

Changing careers will often come with a marked decrease in salary. You don’t just have to worry about shouldering a few extra expenses for the few years it takes your new career to pick up, you also have to worry about retirement.
If your proposed change in career threatens your financial stability, it may be best to tough it out for a chance at a decent retirement fund.

4. Make sure your career isn’t just a ‘passion project’

Starting a new career takes more than a will to succeed, it takes time, skill and talent. Just because you’re passionate about something, doesn’t necessarily mean you’ll be good at it.
A new career will demand that sacrifice a lot of your hobbies and leisure time.
So, before you pick up and move on to what you think will be a better life, consider what you’ll have to give up to succeed.
