The workload was to heavy? If you want to combine two jobs, work either 3 or 4 days for a company, register your own business and work one or two days for yourself. That’s how I manage it. The good side if you have additional income out of your own business is that you don’t have to put any money aside for your retirement, because that would already go via your normal salary. Besides that you also have the luxury of (partially) registering a car, phone on your business or even take debt without any registration (or at least that’s how it’s regulated here). Than there are the many things you are able to buy tax-free such as a laptop or whatever.
The shoulder is great, next week I’ll have a scan. Been training normally, nothing exaggerated but didn’t neglect going to the gym either.
