Re: taking too long for me to troubleshoot!
Speed isn't everything - being thorough and making sure you actually fix the problem is more important than just getting it done fast (unless you're being paid lots to do it quickly/correctly).
As for "tips on being quicker"... that will come with experience, but also depends entirely on the issue you're trying to fix. Some things you'll be able to recognize and fix quickly, others will require research and multiple steps of troubleshooting.
