Focus on quality ASX shares

Warren Buffett once said that "it is far better to buy a wonderful company at a fair price than a fair company at a wonderful price." For investors starting from scratch, that wisdom still rings true.

By prioritising ASX shares with strong business models, talented management teams, and clear competitive advantages, you give yourself the best chance of compounding wealth over the long run.

On the ASX, that could mean blue chip names like CSL Ltd (ASX: CSL), ResMed Inc (ASX: RMD), or Wesfarmers Ltd (ASX: WES) — businesses with proven track records of growth and resilience.

Use ETFs for diversification

If you would rather not pick individual ASX shares, exchange traded funds (ETFs) are an easy way to gain broad exposure to quality companies.

For instance, the Vanguard Australian Shares Index ETF (ASX: VAS) gives you access to the largest 300 shares on the ASX, while the iShares S&P 500 ETF (ASX: IVV) offers exposure to the US market's top 500 stocks, including global leaders like Apple (NASDAQ: AAPL) and Microsoft (NASDAQ: MSFT).

In addition, adding a thematic ETF such as the BetaShares Asia Technology Tigers ETF (ASX: ASIA) or the Betashares Global Cybersecurity ETF (ASX: HACK) could provide further growth potential by tapping into booming sectors like Asian technology and cybersecurity services.

Stay disciplined

The key to reaching $100,000 isn't about chasing hot tips or timing the market — it is about consistency. By sticking to your $1,000 monthly investment, even during periods of market volatility, you allow compounding to do its work.

Over time, steady contributions in quality ASX shares can create powerful momentum, helping your portfolio grow faster than you might expect.

For example, if you can maintain this for just over 6 years, your portfolio would compound its way to $100,000 if you generated an average 10% per annum return.

This is broadly in line with long term share market returns, though it is important to remember that returns are never guaranteed.

Foolish takeaway

With a simple plan you could grow your portfolio to $100,000 in just over six years.

The key is patience, discipline, and a focus on businesses that can stand the test of time.
