Every English verb that's followed by another verb falls into one of three fixed groups: gerund only, infinitive only, or either form.
What you'll learn
When one verb is directly followed by another verb, English forces a choice between the gerund (-ing) and the to-infinitive — and that choice depends entirely on the FIRST verb. Verbs fall into three groups, and memorizing which group a verb belongs to is the only reliable way to get it right.
avoid, mind, suggest, admit, deny, risk, postpone, finish, enjoy, quit, consider, imagine, practice, can't help — always followed by the -ing form, never to + verb.
want, decide, hope, promise, agree, offer, refuse, manage, afford, plan, arrange, fail — always followed by to + verb, never the -ing form.
like, love, hate, prefer, begin, start, continue — these allow both the gerund and the infinitive, usually with little or no difference in meaning.
Admit belongs to the gerund-only group — it's never followed by a to-infinitive.
Refuse belongs to the infinitive-only group — it's never followed by the -ing form.
There's no single rule for every verb — postpone is gerund-only, unlike decide or want, which are infinitive-only.
"Did everyone agree to help with setup?"
"Most people did. A couple offered to bring extra chairs too."
"Great. Let's avoid leaving anything until the last minute this time."
"Agreed — I don't want to risk running out of time again."
