The beauty and curse of an entrepreneur is that you get to do everything by yourself and that you also have to do everything by yourself. At the same time it's really important to outsource things you are not good at and use the time efficiently on the things that you can do well.
During my average day I might update my website answer e-mails from clients, make some proposals, attend to meetings, plan the future, make funding applications among many other things.
I love the fact that I can do what I love and I have freedom to do it when and as I want. It's also really easy make changes on the fly and I don't have to ask permissions from anyone.
The toughest side in this job is big responsibility and sometimes the stress that comes with it. Always a lot of things to handle.
Just do it! Becoming active and networking and getting involved in many different projects. Also to always think about things from different view points.
