Being flexible doesn’t mean you should abandon doing what you love. If you were a full-time dog trainer in your native land, and you want to continue doing that in , go for it. But it may take time to build up a full time dog training career. Don’t expect to get off the boat (or 747) and be greeted by a dozen dog owners all begging for your services. No matter how good you are.
If you’re flexible, you’ll think of other ways to supplement your income.(Work as an assistant in an animal clinic? Provide pet-sitting services? Work in a pet store? Offer dog walking? Take an unrelated job, so you can afford to eat while you build up your training practice?)
If you aren’t flexible, you’ll say, “I’m a dog trainer! If I can’t make a living from this soon, I’m going to give up. I’ll have to take a job I don’t like, and I’ll be stuck. Or I’ll go back to the old country where I can make money.
Of course, this applies to other professions as well, not just to dog trainers. And if you are an accountant or lawyer or doctor, etc. and need to re-certify in , it may take even longer for you to work full time in your field. But it can be done. Stay flexible.
