Is it normal to be this unsure of myself or is this a sign I shouldn’t be considering a PhD?

Letter One: Dear Lost in Academia

If you want to do a PhD, you can also be scared and uncertain and anxious without it meaning it isn’t the right choice for you to make. Many of us, but I’ll mostly speak for myself here, enter PhDs feeling out of our comfort zone, sensitive to failure or perceived failure, or afraid of not being good enough. And we make decisions every month, every week, sometimes hour by hour if those feelings are worth continually feeling and moving through, or if they aren’t.
