We're talking about getting out of bed without procrastinating. If it's difficult, you either haven't had enough sleep or you're being lazy. Getting enough sleep may be difficult, but it's typically not an insurmountable problem. Being lazy is even easier to fix.
Really? Please, do describe your fix for laziness, if it's so easy.
Saying "just be less lazy" is exactly the same as saying "just exert more willpower", and neither is even remotely useful to people whose problems you're belittling as being "just laziness / poor willpower". No therapist would say that to any client for any problem, as they know it would, at best, be completely useless. It's an insult - "you're lazy / weak-willed!" - masquerading as advice.
