Wishful Thinking about Past Research

This year, I started with next to no prior experience in the field of research. I have made incredible progress in learning how to perform research, but now I can't help but wonder what I could've done better or different. It took me a while to understand how and when to use a lab notebook, which caused me immense delays. I had problems with time management, because I hadn't figured out how much effort I had to put in to various tasks. Probably the worst of all, I didn't know how to talk to experienced researchers. If I had known how to talk to a professional researcher, I could have shaved months off my project, but I was too nervous to initiate conversation. All these things would have made my life easier and my research better, but I guess I will just have to keep moving forward. After all, the stress of research were what made my progress so rapid.
