Nothing truly stops you. Nothing truly holds you back. For your own will is always within your control. Sickness may challenge your body. But are you merely your body? Lameness may impede your legs. But you are not merely your legs. Your will is bigger than your legs. Your will needn't be affected by an incident unless you let it.
Caretake this moment. Immerse yourself in its particulars. Respond to this person, this challenge, this deed. Quit evasions. Stop giving yourself needless trouble. It is time to really live; to fully inhabit the situation you happen to be in now.
What ought one to say then as each hardship comes? I was practicing for this, I was training for this.
