What I Used to Do
Past Habits
Used to
'Used to' expresses the idea that something we did regularly in the past is no longer true. It is generally used in the positive form to discuss past habits and routines that we no longer have. 'Used to' can also express a state that is no longer true. 'Used to' is conjugated in the simple past tense, make sure to use the infinitive form in questions and negatives.
Example:
BUT
They used to worry before the production index for durable goods advanced by 2.7% last March.
Did they use to employ an automated wire-guided vehicle?
Would
'Would do' refers to habitual past actions as well. It is more formal than 'used to'. The use of 'would' in questions and negative sentences can easily be misunderstood in a conditional sense, and should therefore be avoided.
Example:
Alex would telephone production management every day at five to report the outputs.
Alex would report on work-in-process products when the orders came in.
