Choosing April goal

Hi Brooke –
I just joined this month and am excited to get started. I am having trouble deciding on my April goal. Do you have any tips on this? I know nothing I choose will be a bad choice, but there are 5-6 things that seem to be equally important. Some seem more challenging to accomplish in one month, especially the goals that require a lot of decision making (which I am just starting to learn to master but definitely not good at yet!). Is it best to really challenge yourself from the very first month, knowing that failure is OK and a great way to learn?
