If you find yourself seemingly addicted to social media, or confined to your job, don't let these bombard you. You're always free to make questions, and take yourself more than what you are. It isn't selfish. Ever.
'Why do I need to think to myself when I think for myself?'
'Why should I care when I do?'
'How does [...] help me if I do?'
'Why do I think I understand this if anyone else can?'
