The re-explanation tax.

Most Claude users pay an invisible tax at the start of every session: re-explaining who they are, what they are working on, and how they prefer to receive responses. Five minutes of re-establishment per session, across fifty sessions in a year, is more than four hours of wasted time. Conversation habits eliminate most of this tax.

When to continue versus start a new conversation.

Continue an existing conversation when:

• You are refining or building on work from the same session
• The prior context is directly relevant to the next request
• You want Claude to maintain consistency across related tasks

Start a new conversation when:

• You are working on a completely unrelated topic
• The prior conversation has grown so long that earlier context is getting pushed out
• You want a fresh perspective without prior thread influence

Projects – your persistent workspace.

Projects keep a set of uploaded files and standing instructions active across every conversation in that Project. For ongoing work – a client account, a writing project, a recurring analysis – this eliminates re-uploading the same reference documents at the start of every session.

Create one Project per distinct area of ongoing work. Write Project instructions that tell Claude the context, the goals, and the working preferences specific to that area. Every new conversation you open in that Project starts with Claude already briefed.

Custom Instructions – your standing professional brief.

Custom Instructions apply to every Claude conversation, across all modes. They tell Claude who you are, how you work, and how you want responses formatted – by default, for every session.

Write your Custom Instructions to cover:

• Your professional role and relevant background
• Your communication preferences (brevity, bullet points, no summary at end)
• Your current primary focus
• Any standing constraints (no jargon, match this style, always ask before assuming)

The feedback habit.

Within any conversation, give Claude real feedback. "That's too long," "the tone is too formal," "I needed examples here, not theory," "good – now make it half as long" are all legitimate responses. Claude adjusts immediately. Treating a response as a draft and giving targeted feedback is more efficient than accepting what you receive or starting over.
