Now that your arrival has been registered with the Equestrian government and you have a temporary place to bunk for the night, you can get on with the business of day-to-day life with talking ponies for neighbors and co-workers.
Yes. You actually have to work for a living here.
While ponies are tough for their adorably tiny size (compared to us humans) a human has some respectable muscle to throw around, and is capable of feats of manual dexterity that only unicorns can exceed with magic. Ponies are slowly warming up to the idea of hiring human workers, and barring certain fields (based on technologies that do not exist here) there is a small but growing range of employment opportunities.
For those humans proven trustworthy and capable, there is very rewarding, but extremely dangerous work in the Equestrian military. Borders must be patrolled, monsters slain or driven off, and ponies escorted through the wilderness on various journeys.
Human art and music has received a varied reception so far, and I stress the need for you to contact existing schools, studios and performing groups to learn about the local trends, tastes, tools, and materials involved in Equestrian artistry. It is not impossible for the artistically inclined to make a living here, once you know what you're working with.
Ponies have no particular aversion to advanced technology, considering it little more then another sort of magic. However, by Royal Decree, Human scientists must abide by a similar system of licensing and oversight that Unicorns are regulated by when engaged in potentially dangerous magical experimentation.
This generally requires providing an overview of what you are creating or hoping to accomplish, any potential dangers or side-effects, etc. Unless the process or result is deemed too dangerous, polluting, or disruptive to society, the license is likely to be issued.
Speaking of technology, you'll find Equestria to exist somewhere along early Renaissance lines, but deficient in some areas and highly refined in others. Having magic meant many technologies were deemed redundant and never developed. On the other hand, magic could substitute for tools and power sources that were otherwise impossible to build at that level of technology, allowing experimentation and construction of some impressive techno-magical devices. But be aware that the high magical ambiance also interferes with and tweaks many phenomena and processes, whether chemical, technological, or physical. Otherwise, the laws of physics act mostly as you expect them to.
I stress the 'mostly' part. The chapter on magic has more details.
